Equipment for recording and playback of bat echolocation and communication calls

Passive Monitoring / Bat Recorders

Passive bat monitoring systems (based on the Avisoft UltraSoundGate technology and the RECORDER USGH software) are now manufactured and distributed by our cooperation partner bat bioacoustictechnology GmbH.

The following components for special applications are still available from Avisoft Bioacoustics:

#40040 Low-cost bat monitoring system with phantom-powered electret microphone

#54163 Avisoft-UltraSoundGate 416Hnbm
#64163 (64164) Avisoft-UltraSoundGate 416Hb

#40001 Electret Ultrasound Microphone Knowles FG
#40007 Electret Ultrasound Microphone Knowles FG-O
#40011 Condenser ultrasound microphone Avisoft-Bioacoustics CM16/CMPA (not compatible with 416Hnbm)

#10101 (10102) Analysis software Avisoft-SASLab Pro

All recording system variants include the Avisoft-RECORDER software that comes with a Bat Call Trigger Filter, which can prevent triggering on unwanted broad-band noise such as wind, rain or insect stridulations. In contrast to a few other brands claiming such functionalities, the Avisoft Bioacoustics solution to this problem just works efficiently under real-world conditions!

What the experts say

“It’s widely recognized in the bioacoustics community that Avisoft Bioacoustics designs the best commercial systems for recording, digitizing, and analyzing the biosonar and social calls of bats. Brock Fenton’s lab at University Of Western Ontario has worked with, and tested, the major commercially-available bat recording systems. In acoustic monitoring, Avisoft systems outperform others, recording 7-60% more free-flying bat calls than other systems (Batlogger, AnaBat, Batcorder and Song Meter)*. For behavioral research use, I have found that Avisoft recording and playback systems are the most powerful and user-friendly. I have tested bioacoustic equipment from several companies, but I always come back to Avisoft because of the time-tested reliability, durability, ease of use, and the state of the art capabilities. One of the biggest advantages is the superb customer service. Over the last few years, I’ve sent Raimund Specht dozens of email questions and inquiries. He has always been very patient, courteous, helpful, and fast to respond. This is clearly a company that sets the highest standards of quality and customer support.”
